This is the latest (main) BeagleBoard documentation. If you are looking for stable releases, use the drop-down menu on the bottom-left and select the desired version.

Introduction

BeagleBone AI-64 like its predecessors (BeagleBone AI), is designed to address the open-source Community, early adopters, and anyone interested in a low cost 64-bit Dual Arm® Cortex®-A72 processor based Single Board Computer (SBC). It also offers access to many of the interfaces and allows for the use of add-on boards called capes, to add many different combinations of features. A user may also develop their own board or add their own circuitry.

Note

AI-64 has been equipped with a minimum set of features to allow the user to experience the power of the processor and is not intended as a full development platform as many of the features and interfaces supplied by the processor are not accessible from BeagleBone AI-64 via onboard support of some interfaces. It is not a complete product designed to do any particular function. It is a foundation for experimentation and learning how to program the processor and to access the peripherals by the creation of your own software and hardware.

BeagleBone Compatibility

The board is intended to provide functionality well beyond BeagleBone Black or BeagleBone AI, while still providing compatibility with BeagleBone Black’s expansion headers as much as possible. There are several significant differences between the three designs.

Fig. 55 BeagleBone AI-64 board components

  • DC Power is the main DC input that accepts 5V power.

  • Power Button alerts the processor to initiate the power down sequence and is used to power down the board.

  • GigaBit Ethernet is the connection to the LAN.

  • Serial Debug ports WKUP_UART0 for early boot from the management MCU and UART0 is for the main processor.

  • USB Client is a USB-C connection to a PC that can also power the board.

  • BOOT switch can be used to force a boot from the microSD card if the power is cycled on the board, removing power and reapplying the power to the board.

  • There are five green LEDs that can be used by the user.

  • Reset Button allows the user to reset the processor.

  • microSD slot is where a microSD card can be installed.

  • miniDP connector is where the display is connected to.

  • USB Host can be connected different USB interfaces such as Wi-Fi, Bluetooth, Keyboard, etc.

On bottom side we have,

  • TI TDA4VM processor.

  • 4GB LPDDR4 Dual Data Rate RAM memory.

  • Ethernet PHY physical interface to the network.

  • eMMC onboard MMC chip that holds up to 16GB of data.
